It runs linux, so it is  able to do anything you can do with
linux. (Within the limited processing power of the device.)
You may have to set this up yourself though, I am
not aware of anyone experimenting with encrypted filesystems.

You can plug in any USB device that linux supports.  I don't know if the 
device is fast enough to actually encrypt and store a video stream 
though. You might want to consider a really small PC like an acerONE. It 
even has a built-in webcam.

Yes, this works fine. GPRS isn't very fast though.

Probably not over GPRS - not enough bandwith for video! Wifi has
enough bandwith, if you are within range of an access point.

Turning off GSM means they can't find your position using the GSM 
network any more. They still know where you were, when you turned
it off though.

I am not sure you can force a connection to a faraway tower, and it
certainly won't help you. The other towers still see the better
signal strength, so your location is still known.

What part of Europe would that be? Definitely not western Europe.
